INNOVATION FOR YOUR RIDE

Speed Evolution is a company created by Bear Valley Bikes owner Derek Hermon to provide a full array of innovative cycling products which mechanically enhance bike performance. Speed Evolution’s original product was the Speed Lube, an unique formula that synergistically cleans and lubricates your bike’s components. Next came the tubeless aluminum valve stems. Our presta valves are lightweight and are designed with a larger diameter to provide both increased airflow and a better seal. Now available in 9 different anodized colors and 3 different lengths, they are a perfect addition to any customized bicycle. Derek then moved forward in creating a 40mm presta valve extender and also a more robust schrader valve. Finally, for the ultimate performance, Speed Evolution “Super Sauce” sealant was created to work in perfect harmony with the tubeless valve stems, achieving a winning combination of high performance and reliability.    We are dedicated to mechanically enhancing your ride and also sell some of our favorite accessories to do this that best compliment our products.
